To paraphrase PioneerSchmioneer in a previous thread, ‘you are wrong because you broke the rules’. Appeal to authority, especially one’s own authority, with no direct bearing on the content discussed is fallacious and particularly arrogant, and common among particular styles of academia where such people lose sight of a legitimate interest in truth in favour of self-importance and tradition. And he threw in some ad hominem on top for ‘good measure’, including straw manning motivations and poisoning the well. Pathetic.
It is entirely unimpressive to say a particular interpretation is wrong (or likely wrong) because it isn’t consistent with some other self-important (and often biased) interpretation. It is much more helpful to assess interpretations based on content, historical context, comparison with other sources to which the authors had access, and the probable motivations of the authors.
